I know it's a dirty workaround, anyway here it is some useful info. Just a note: I'm using a late 2011 iMac, with triple boot (OSX, Windows 10, Ubuntu), and using refind as boot manager. I was using Ubuntu 16.04 before this upgrade.
If you need additional info, I'm happy to contribute! root@headache:~# cat /etc/fstab # / was on /dev/sdb5 during installation UUID=7a938125-aa7c-4c10-ac1a-d3e941b93960 / ext4 errors=remount-ro 0 1 # /boot/efi was on /dev/sda1 during installation #UUID=70D6-1701 /boot/efi vfat umask=0077 0 1 # swap was on /dev/sdb6 during installation UUID=55df36ca-4888-46a7-bc9f-ec71dd8caa23 none swap sw 0 0 root@headache:~# uname -a Linux headache 4.10.0-28-generic #32-Ubuntu SMP Fri Jun 30 05:32:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux root@headache:~# [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS UEFI -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1707497 Title: package shim-signed 1.32~17.04.1+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: il sottoprocesso installato script di post- installation ha restituito lo stato di errore 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1707497/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
